Yo they could put these in the game... you only fire the flame thrower, and every time you hit someone they light on fire... takes 10 seconds to reload, but when you fire you get 2-3 seconds of constant fire that you can rotate around anyway you want, potentially setting multiple tanks ablaze, forcing them to use the extinguishers, and then doing it again in 10 seconds, and maybe even a 3rd time if they carry two extinguishers... Hopefully by the 3rd-4th time they'd be dead from burning out, or at least be rendered "combat ineffective"...

That would make SPG "Cancer" seem like a band-aid being ripped off compared to that kind of cancer...

POA-CWS-H5 flamethrower tank, with the 105 mm howitzer and flame gun mounted coaxially; howitzer ammunition stowage was reduced to 20 rounds. Its designation stands for the Pacific Ocean Area, with the flame gun developed by the Chemical Warfare Service in Hawaii. This design replaced the previous POA-CWS-H1 that had the flame gun replacing the tank's regular armament. The POA-CWS-H5 could be constructed from either 75mm gun or 105mm howitzer tanks, but the design missed seeing action in World War II. The Marines employed a single platoon of nine 105 mm howitzer POA-CWS-H5 tanks in the Korean War attached to the Headquarters and Service Company of the First Tank Battalion. The crew was reduced to four Marines due to the space taken up by the flame equipment, with the TC inheriting the role of gunner as well.

If my 1:16 scale Tamiya radio controlled Sherman is accurate, then that barrel is definitely a 105. My model is a 105 and the diameter of the barrel and it's length is identical to what is shown in that photo.
